Abstract[English] Methods and apparatuses for encoding and decoding a physical layer (PHY) protocol data unit (PPDU) for low power indoor (LPI) wireless communication, which includes a preamble portion and a payload portion. The preamble portion includes a first universal signal field (U-SIG), the first U-SIG comprising information regarding a payload portion of the PPDU. The preamble portion further includes a second U-SIG, which contains identical information regarding the payload portion of the PPDU. The repetition of the U-SIG may improve robustness of the preamble portion detection and also enable auto-detection of the PPDU for LPI communication.[French] L'invention concerne des procédés et des appareils de codage et de décodage d'une unité de données de protocole (PPDU) de couche physique (PHY) pour une communication sans fil d'intérieur à faible puissance (LPI), qui comprend une partie de préambule et une partie de charge utile. La partie de préambule comprend un premier champ de signal universel (U-SIG), le premier U-SIG comportant des informations concernant une partie de charge utile de la PPDU. La partie de préambule comprend en outre un second U-SIG, qui contient des informations identiques concernant la partie de charge utile de la PPDU. La répétition de l'U-SIG peut améliorer la robustesse de la détection de la partie de préambule et également permettre l'auto-détection de la PPDU en vue d'une communication LPI.
